CpeT family
Description
CpeT from the Prochlorococcus marinus MED4 cyanophage P-HM1 was biochemically characterized and its structure resolved at 1.8-Å (Protein Data Bank ID: 5HI8). It attaches a PEB at Cys-155 of beta-PEI (Gasper et al. 2017) and perhaps at the corresponding position in beta-PEII of marine Synechococcus cyanobacteria. CpeT was also characterized in the red alga Gracilariopsis lemaneiformis as a PEB:Cys-158 beta-phycoerythrin lyase (Cao et al. 2019).
